Authorize.Net is a favorite payment mode used in web development. It is simple, easy and secure payment connection. I use authorize.Net in my codeigniter based projects and here is the code.

This is helper for payment.

function do_payment ($post_values)
{
        $post_url = "https://test.authorize.net/gateway/transact.dll";  
        // This section takes the input fields and converts them to the proper format
$post_string = "";
foreach( $post_values as $key => $value )
{ $post_string .= "$key=" . urlencode( $value ) . "&"; }
  $post_string = rtrim( $post_string, "& " );

// This sample code uses the CURL library for php to establish a connection,
// submit the post, and record the response.
// If you receive an error, you may want to ensure that you have the curl
// library enabled in your php configuration

$request = curl_init($post_url); // initiate curl object

curl_setopt($request, CURLOPT_HEADER, 0); // set to 0 to eliminate header info from response

curl_setopt($request, CURLOPT_RETURNTRANSFER, 1); // Returns response data instead of TRUE(1)
curl_setopt($request, CURLOPT_POSTFIELDS, $post_string); // use HTTP POST to send form data
curl_setopt($request, CURLOPT_SSL_VERIFYPEER, FALSE); // uncomment this line if you get no gateway response.
$post_response = curl_exec($request); // execute curl post and store results in $post_response

// additional options may be required depending upon your server configuration
// you can find documentation on curl options at http://www.php.net/curl_setopt
curl_close ($request); // close curl object

// This line takes the response and breaks it into an array using the specified delimiting character
$response_array = explode($post_values["x_delim_char"],$post_response);

// The results are output to the screen in the form of an html numbered list.
if($response_array)
{
return $response_array;
}
 else { return ''; }
}

And here is your controller function:


function do_user_payment()
{
     $this->load->library('auth_payment');
     $card_expiration = $_POST['crMonth'].$_POST['crYear'];

     $x_login   = "login_key";
     $x_tran_key  = "trans_key";
     $card_number = $_POST['ccn']; 

     $invoice_num = '';

     $x_card_code = $_POST['CSV'];

     $post_values['x_invoice_num'] = $invoice_num;
     $post_values['x_login'] = $x_login;
     $post_values['x_tran_key'] = $x_tran_key;

     $post_values['x_card_code'] = $x_card_code;

      $post_values['x_version'] = "3.1";
      $post_values['x_delim_data'] = "TRUE";
      $post_values['x_delim_char'] = "|";
      $post_values['x_relay_response'] = "FALSE";

      $post_values['x_type'] = "AUTH_CAPTURE"; //Optional
      $post_values['x_method'] = "CC";
      $post_values['x_card_num'] = $card_number;
      $post_values['x_exp_date'] = $card_expiration;
      $post_values['x_amount']   =  'Your Charges';

      $post_values['x_first_name'] = $user_first_name; //Optional (From Client)
      $post_values['x_last_name'] = $user_last_name; //Optional (From Client)
      $post_values['x_address'] = $user_address1; //Optional (From Client)
      $post_values['x_state'] = $user_state; //Optional (From Client)
      $post_values['x_zip'] = $user_zip; //Optional (From Client)

      //Calling Payment function

     $paymentResponse = $this->auth_payment->do_payment($post_values);

     if($paymentResponse[0]==1 && $paymentResponse[1]==1 && $paymentResponse[2]==1)
     {
          // payment is successful. Do your action here
     }
    else
     {
          // payment failed.
          return $paymentResponse[3]; // return error
     }
}

  1. I agreed that Authorize.Net is one of the best and well- known payment mode which used for web development. Although, I had used Merchant Inc www.merchantinc.com and it was also helpful for payment such as Authorize.Net. I liked the whole content to read.
